Is it possible to get element from HashMap by its position?

Question

How to retrieve an element from HashMap by its position, is it possible at all?

Answer 1

Use a LinkedHashMap and when you need to retrieve by position, convert the values into an ArrayList.

LinkedHashMap linkedHashMap = new LinkedHashMap();
/* Populate */
linkedHashMap.put("key0","value0");
linkedHashMap.put("key1","value1");
linkedHashMap.put("key2","value2");
/* Get by position */
int pos = 1;
String value = (new ArrayList(linkedHashMap.values())).get(pos);
